Solar energy
The scenario of Brazilian countryside Things are changing. Where there used to be soybeans, sugarcane, or pasture, rows of solar panels are now appearing. The transformation is visible, especially in northwestern Paraná. And it’s not just an environmental trend. It’s a business strategy.
Farmer Mauro Dias Lima, from Paranavaí, decided to lease part of his property to a solar power plant. The logic is simple: diversify revenue and reduce risks. “It’s another income option,” explains Mauro. “Before, we leased the land for sugarcane, soybeans, and cassava. Today, we have solar panels producing energy instead of crops.”
Thus, agribusiness is now also acting as a generator of clean energy. In addition to food production, the countryside is now “planting” electricity.
Soaring electricity bills are driving people to seek out technology that integrates solar energy and batteries, which can pay for itself in 24 months and helps reduce peak demand.

China floods the market with cheap solar panels and creates a new energy boom: walls and fences are now being transformed into mini-power plants, challenging the logic of rooftops.

This movement is not isolated. Paraná already occupies the third position in the national ranking of solar power generation, with 8,7% of Brazilian production, according to the Brazilian Photovoltaic Solar Energy Association (Absolar). It is behind only São Paulo, with 15,5%, and Minas Gerais, with 12,2%.
According to Liciany Ribeiro, executive director of Absolar, the northwestern region of the state concentrates several power plants. The climate is favorable. Proximity to distribution networks is also a factor. “Investors build the plants and sell the energy to cooperatives. This makes the process viable and guarantees cheaper and more accessible energy for the end consumer.”
Since 2012, the solar sector in Paraná has generated over R$ 15,2 billion. Furthermore, it has created approximately 99 direct and indirect jobs. These figures are striking and help explain why more producers are adopting solar panels.
Meanwhile, in Mato Grosso do Sul, the progress is even faster. According to a survey by the startup 77Sol, the state leads the national ranking for distributed solar power generation.
The explanation lies in the very nature of the field. Dairy, swine, and poultry producers depend on a constant energy supply. Drops or fluctuations can cause losses. “Dairy, swine, and poultry producers face constant fluctuations in the electrical grid. For them, solar energy, combined with storage systems, guarantees stability, preventing losses and damages,” says Germano Lima Rodrigues Caires, of Evo Brasil – Energia Fotovoltaica and president of the South Mato Grosso Distributed Generation Front.
Furthermore, the state has one of the highest energy rates in the country. Therefore, investing in solar panels becomes financially attractive.
With expansion, the use of hybrid systems is also growing. These combine solar panels with batteries and special inverters. The goal is to store energy produced during the day for nighttime use or during periods of low generation.
“This is an essential advancement for agriculture,” explains engineer Marcelo Niendicker. “The batteries reduce dependence on the electrical grid and eliminate the use of diesel generators, allowing for a more sustainable and profitable operation.”
Data from the International Energy Agency indicates that battery prices have fallen by 85% in recent years. This further boosts the market. The expectation is that the adoption of lithium batteries will grow by 30% annually until 2030.
At the same time, international companies are expanding their presence in Brazil, bringing technology and certifications. The agricultural sector, which has always been synonymous with food production, is now assuming a strategic role in the energy transition.
